' (dini/it %iaa latent dition Letters Patent No. 111,762, dated February 14, 1871.

IMPROV EMENT lhiCOMBINE-D KEY-RINGS AND DQOR-FASTENERS.

The Schedule referred to in these Letters Patent and making part of i'hesme.

To all 'whom 'it may con-cern Be it known thatALmBnYnNfr H. MELnNoY, of Manchester, in' thefcounty of- Hillsborough and State of New Hampshire, have inventeda new and nsefulrnprovement in Combined Key Ring and Door-Fastener; and Ido hereby declare that the fol` lowing is a full, clear-,and exact description thereof, which will enable others skilled in the art to 'make and use the same, reference being had tothe accompanying drawing forming part of this specification.

Figure l'is a detail longitudinal section of my iinproved key-ring and door-fastener. v Figure 2 is a sideview of the same in position for fastening a door, and showing thevcompensator in p laee.

i Figure 3 isjthe saine view as fig. 2, but showing the compensator in another position,.and having parts broken away to show the construction.

Figure 4 is a detail cross-section of the same, taken thronglf the line xx, iig. 3.

Similar letters of reference indicate corresponding parts.

v My invention has for its object to improve the construction of iny improved key-ring and door-fastener, patented May 17, 1870, and July 19, 1870, and numbered 103,068 and' 105,474, so as to make it lighter, stronger, smaller, and better, and thus more convenient and effective in use; and

My invention consists in combining the shoulders upon the inner part of the hook or claw withrece'ssed and shouldered spaces upon the under side of the main frame, when the hook is held in place bya spring-arm; and I It also consists in making the Acompensator detach able, in the manner shown .in the drawing, and hereinater described.

A are the side pieces that form the body of the device, which are connected to each other and held in their proper relative positions by the rivet B at their rear ends and by the stay G at their forward ends.

The edges ot' the rear parts of the Apieces kA are out, away, as shown in gs. 1, 2,.. and 3, to form bearings n.1 for the shoulders of the hook D.

The forwardrends of the pieces -A have notches or slots h2 formed in them to receive the shoulders of the hook D, when the device is closed for carrying in the pocket.v i

rlhe hook D has a hook orelaw [l1 formed in its forward end to be forced into the door casing in fastening the door, and shoulders d2 to enter the notches a? of the pieces A, and which also strengthen the claw d1.

Upon the side edges of the other end of the hook D are formed shoulders d, which slide along the bearings .a in adjusting the device for fastening the door.

The rear .end of the hook D has a notch d* formed init to receivethe 'spring E, by which the said hook D is held in place .when fastening the door.

The other end of thespring D projects so as to press against the hook D and hold it in place when closed.

The body of the hook D is bent, as shown in gs. 1, 2, and 3, to give it a suitable shape for operating properly in its different positions.

11 is the spring-arm, upon which the keys are strung, and which is made in about the shape shown in figs. l, 2, and 3.

One end of the spring-arm F is hinged to the pivot B; and its other end is bent to form a hook, f1,which locks into the open end of the stay O.

, The-stay C is made Ufshaped, and ,with projections o upon the side edges of itsv bent vend by means of which .it is riveted to the pieces A, as vshown in gs. 1, 2, and 3.

, G is the compensator, which is made with a hole in its rear end, by means of which, when not'desired for use, it may be strung upon the spring-arm F, which enables it, whenl required for use, to be turned or slipped over the rear ends 'of the pieces A, as shown in figs. 2 and 3.

The compensator G is made with hooks, lips, or

flanges g gz upon its forward and rear ends to keep it in place when adjusted for a narrower or wider crack between the door-easing and the forward edge of the door.

When the said crack or space is too wide for the door to force the claw ll of the hook D suii'iciently far into the door-casing` to hold rmly, the compen sator Gr is adjusted with its flange gl overlapping thc claw d1 of the hook D, with its ange q2 resting against therear side of the otherend of the hook D and its rear end between the spring E and the edges of the pieces A, as shown in g. 2, so that the body of the compensator may rest squarely against the body of thevhook-D.

lVhen the said crack is still too wide for .the door to force the claw d* firmly into the casing the cornp'ensator G may be arranged with its forward flange gl resting against the rear side of the hook D, the spring E in this case passingthrough the hole in the said compensator G, as shown in fig. 3.

Having thus described my invention,

I claim as new and desire to secure by Letters Patent- 1. The* hook D, held in place'by a spring-arm,

'its ends, in combination with hook D, pieces A,

and having shoulders el on the inner part thereof, spring E, and springnrrn F, substantially as herecombined as described, with the pieces A, having in shown :md described, and for the purposes set recesses and shoulders al thereon, for the purpose forth. specified.

'2. The compensator, G, constructed with :L hole in its rear end and with lips or flanges g g2 upon BRYANT H. MELENDY.
